Pseudo-classical vs. “The JavaScript way”

Question

Just finished reading Crockford\'s \"JavaScript: The Good Parts\" and I have a question concerning his stance on the psuedo-classical vs. prototypal approaches.

Answer 1

The prototypal variant for the example you have looks like the following in my understanding:

Object.beget = function (o) { /* Crockfords replacement for the new */ }

var myModule = {
    something : null,
    getSomething : function () {},
    setSomething : function () {},
    doSomething : function () {}
};

And then you can do:

var foo = Object.beget(myModule);
foo.something = bar;

UPDATE: You can also use the builder pattern to replace a constructor like this:

var myModuleBuilder = {
    buildMyModule : function (something) {
        var m = Object.beget(myModule);
        m.something = something || {};
        return m;
    }
}

so then you can do:

var foo = myModuleBuilder.buildMyModule(something);
